We previously reported that a 4.2 kb SacI-EcoRI DNA region from Streptomyces kasugaensis M338-M1, a kasugamycin (KSM) producer, included KSM transporter genes (kasKLM). As an extension of that study, a 3.7 kb Psti-SacI DNA region, located at 1.5 approximately 5.2 kb upstream of kasK, was cloned and sequenced, revealing three complete open reading frames,(More)
Destruxin E (DE), a cyclodepsipeptide isolated from fermentation broths of Metarhizium sp. MA324, inhibited the growth of v-Ki-ras-expressed pMAM-ras-REF (rasREF) cells in the suspension (anchorage-independent) culture (a) more strongly than that in the substratum-attached (anchorage-dependent) culture (b) or that of v-Ki-ras-unexpressed pMAM-ras-REF (REF)(More)
Streptomyces kasugaensis M338-M1 produces the aminoglycoside antibiotic kasugamycin (KSM). We previously cloned, sequenced and characterized the KSM acetyltransferase, transporter, and some of the biosynthetic genes from this strain. To identify other potential genes in a chromosome walk experiment, a 6.8-kb EcoRI-PstI region immediately downstream from the(More)
Iron regulatory protein-1 (IRP-1) is known as a cytosolic aconitase and a central regulator of iron (Fe) homeostasis. IRP-1 regulates the expression of Fe metabolism-related proteins by interacting with the Fe-responsive element (IRE) in the untranslated regions of mRNAs of these proteins. However, it is less known whether IRP-1 modulates various non-Fe(More)
